After less than a week from achieving the Google Associate Cloud Engineer certification, I took the Google Professional Cloud Architect exam.
Preparing this exam, I found odd the fact that Google provides three case studies to bring to the exam. I was even more impressed by the number of questions around those cases. It felt odd since it felt like you could prepare very well those three case studies and be advantaged in the exam. Overall, I think that this is not the case, since having prepared the cases, will only help you not having to re-read the whole case before answering the questions. Also, I found myself to read the case name, read the question, read the answers, choose the answer, and then read the case text again, just to be sure.
Differently from the Google Associate Cloud Engineer, in the Google Professional Cloud Architect exam, there is often more than one answer that seems right at first sight, and only analyzing the words more precisely you can rule out answers until you arrive at the right one. Another big difference I found from the Google Associate Cloud Engineer certification, is that the Google Professional Cloud Architect exam can not be passed with just learning theoretical concepts, since it requires real-world experience both on the technical side, and in the ability to understand the business requirements of an ICT system, even if not completely expressed.
I enjoyed the certification and I would recommend it to anyone that wants to start doing Cloud Architecture or is already a Cloud Architect and wants to be certified.
